To all whom/it ma;y con/centi- I I I Be it known that 1, Mann}? Fisonnn, a' citizen of the Republic of Swit'zerlandfresid- ,ing at Zurich, in Switzerland, have invented new and useful'lmprovements in Motorvehicles Having Friction-Disk Driving Gear, of

' whichthe following is a'specifioation.

This invention relates to amotor-vehicle' having friction-disk driving-gear, in which the pressure of the friction-wheel against the I friction-disk is increased according to the'increasing traveling resistance. For this purpose the shaft of the frietion-wheelis pivoted-t. e., is formed as a lever upon which the driving-chain so acts that inproportion to the increasing traveling resistance the frietion-wheelshaft is caused to turn about its '2 is a side view. Fig. 3 shows a detail.

point of rotation, and so press the frictions wheel againstthe friction-disk. 1

An example-of aconstructional form ofinotor-vehicle according to this invention is shownin'the accompanying drawings, which, however, only lllustrates the parts necessary to the'explanation of this invention.

Figure 1 is a plan'view of the vehicle. Fig.

' The drawings show a vehicle in'which the motor a, is built in at the front. Upon the shaft of the motor is mounted a friction-disk against which a friction-wheel c is pressedu This wheel is mounted upon a shaft d, which by being journaled-to the vehicle-frame e at f forms a double-armed lever upon one arm of which the wheel a is mounted and upon the other arm of which is secured a chain-wheel. gm connection through a driving-chaln h with a chain-wheel i, fixed on the rear vehia bearing m,;arranged beneath the frame is a plate arranged to slide upon the vehiole-frame guided by pins Z, and which'carrie's for the adjacent end portion of the shaft d. To

one end of the plate It is attached a drawspring n and to the other'end a linko, which.

is connected to one arm of an adj listing-lever p, pivoted on the vehicle-frame.

Through the intervention of the frictiondisk I) the motor a drives the friction-wheel c, the shaft d, the chain-wheel g, the driving chain it, and the chain-wheel 'i on the rear axle of the vehicle. If now an increase of the traveling resistance arises, the 1111 of the chain It upon the chain-wheel g an upon the lever formed by the shaft. dis augmented. so

' that the friction-wheel c is pressed against the frlction-disk b with a greater pressure corresponding to the increased traveling r'esistance. By movement of the adjustinglever 10 in the direction of the arrow the platelcwill be drawn-back against the action of the spring a and the lever formed by the .shaft (1 so moved about its pivot f that the friction-wheel 0 will be drawn out of contact with the friction-disk b for the'pu'rpose of stopping the vehicle. The spring a after releasing the adjusting-lever p efi'ects a return movement of the parts into the operative position.

Having now particularly described and ascertained the nature of the said invention and in "what. manner'the same is to be performed, I declare that what I claim is- 1. In a motor-vehicle a driven frictiondisk in combination with a shaft and frictionwheel slidable thereon, rontacting Withand driven by the disk, means to pivotally mount the shaft near one end and meansto slidably niount the other end of the shaft,a drivingpinion on thesha'l't, and a road-wheelchain connected tothe pinion, said-shaft free to move on its pivot by reason of the tractive' force of the road-wheel, whereby the pressure of the friction-wheel against the disk will in.- orease with said tractive fOl'fl.

2. In a motor-vehicle ,a driven i'rictiondisk in combination with a shaft and'a l'riction-wheel slid'ably mounted thereon eontaeting with and driven by the frietion-disk,

a pivoted bearing near one end of the shaft and a slidable bearing near the, other end of the shaft, aspring to urge this bearing toward the planeof the friction-disk, an actuating -lever connected to this hearing to move it against the stress of its spring awayfrom the disk, at driving-pinion on the shaft. p
